Description
Technical field
The utility model relates to cable technology, is specifically related to the cable of a kind of large span, heavy in section, large ampacity.
Background technology
Existing cable, generally adopts zinc-coated wire as core, the aluminum steel of outer stranded circle.Mainly there is the problem of following several respects in this cable: one, due to skin stranded be circular aluminum steel, cause the gap of etween the lines large, net sectional area is little, and external diameter is large, store and transportation in take up room greatly.Two, uneven, rough by the stranded superficies that form of circular aluminum steel, easily pile up ice and snow or other heavy burden materials, increase the heavy burden of cable, anti-ice-snow ability, easily bends and destroys cable.Three, the tensile strength of zinc-coated wire used is low, and weight is large, and while setting up, span is less, sets up the required shaft tower quantity of cable many, and not only cost is large, wasting manpower and material resources, and also land occupation resource is many.
Based on above problem, existing cable cannot meet the new demand of power construction fast development.
Utility model content
In view of this, the utility model aims to provide that a kind of net sectional area is large, ampacity is large, anti-ice-snow function admirable, span is large, power transmission efficiency is high and energy-conservation, set up the stranded carbon fiber aerial cable of bow type aluminum steel that cost is low.
The utility model takes following technical scheme to address the above problem:
Bend the stranded carbon fiber aerial cable of type aluminum steel, comprise conductor sandwich layer and stranded coated skin outside described conductor sandwich layer.Wherein, described conductor sandwich layer is formed by carbon fiber complex core.Described coated skin is stranded formation of aluminum steel of bow type by many cross sections.The cross section of described coated outer field outer surface is full circle.Between described conductor sandwich layer and described coated skin, there is preset clearance.
Preferably, the tensile strength of described carbon fiber complex core is more than or equal to 2940MPA.
Preferably, described conductor sandwich layer comprises a carbon fiber complex core.
Preferably, described coated skin comprises that 8 cross sections are the aluminum steel of bow type.
Compared with prior art, the beneficial effect of the stranded carbon fiber aerial cable of bow type aluminum steel of the present utility model is:
The stranded carbon fiber aerial cable of bow type aluminum steel of the present utility model utilizes the stranded formation conductor of carbon fiber complex core sandwich layer, thereby greatly improved the tensile strength of overhead power transmission cable, and lightweight, can realize large span built on stilts and improved ampacity, the required shaft tower quantity of overhead power transmission cable reduces, greatly reduce the costs such as manpower and materials, and land resource is few; And, utilize the stranded formation of aluminum steel that many cross sections are bow type coated outer, the cross section of described coated outer field outer surface is full circle, thereby not only further improved ampacity, and make the smooth surface of overhead power transmission cable, effectively improved anti-ice-snow performance, and surface is difficult for adhering to dust, can effectively reduces noise and line loss that corona discharge produces; And, between described conductor sandwich layer and described coated skin, there is preset clearance, make composite cable there is excellent self-damping effect, reduced the vibration in composite cable running.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the stranded carbon fiber aerial cable of bow type aluminum steel of the present utility model.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, the utility model provides a kind of stranded carbon fiber aerial cable of type aluminum steel that bends, and comprises conductor sandwich layer 10 and at described conductor sandwich layer 10 outer stranded coated outer 20.Wherein, described conductor sandwich layer 10 is formed by carbon fiber complex core 12.Described coated outer 20 is stranded formation of aluminum steel 22 of bow type by many cross sections.The cross section of described coated outer 20 outer surface is full circle.Between described conductor sandwich layer 10 and described coated outer 20, there is preset clearance.
Particularly, in described conductor sandwich layer 10, the tensile strength of carbon fiber complex core 12 is more than or equal to 2940MPA.Adopt the carbon fiber complex core 12 of above-mentioned tensile strength to strengthen the ability of overhead power transmission cable load-bearing, lightweight, 1/4 of the not enough steel of proportion, met the requirement of large span and heavy in section high pressure, ultra high voltage, greatly reduce the shaft tower cost in new line construction, saved valuable land resource and human resources.And carbon fiber complex core 12 has zinc-coated wire incomparable excellent resistance to elevated temperatures and decay resistance, has guaranteed the stability of overhead power transmission cable in During Process of Long-term Operation.
In in this enforcement, described conductor sandwich layer 10 comprises a carbon fiber complex core 12.Described coated outer 20 comprise the aluminum steel 22 that 8 cross sections are bow type.
The stranded carbon fiber aerial cable of bow type aluminum steel of the present utility model adopts many full circle of the stranded formation of aluminum steel 22 that cross section is bow type, make overhead power transmission cable surface smooth and tight, there is good anti-ice-snow ability, and surface is difficult for adhering to dust, can effectively reduce noise and line loss that corona discharge produces.And amass this stranded effective cross section that can greatly increase closely, has improved the ampacity of overhead power transmission cable, ampacity is than adopting circular aluminum steel to improve more than 60%, and total body diameter of overhead power transmission cable reduces by 20% left and right than the circular aluminum steel of employing.
In addition, the stranded carbon fiber aerial cable of bow type aluminum steel of the present utility model can leave certain gap between the layers, makes overhead power transmission cable have excellent self-damping effect, has reduced the vibration in overhead power transmission cable running.
Compare with traditional like product, the stranded carbon fiber aerial cable of bow type aluminum steel of the present utility model can meet the construction of heavy in section high pressure, extra high voltage line, has reduced the loss of electric power in transmission, has improved power transmission efficiency.
The stranded carbon fiber aerial cable of bow type aluminum steel of the present utility model utilizes the stranded formation conductor of carbon fiber complex core sandwich layer, thereby greatly improved the tensile strength of overhead power transmission cable, and lightweight, can realize large span built on stilts and improved ampacity, the required shaft tower quantity of overhead power transmission cable reduces, greatly reduce the costs such as manpower and materials, and land resource is few; And, utilize the stranded formation of aluminum steel that many cross sections are bow type coated outer, the cross section of described coated outer field outer surface is full circle, thereby not only further improved ampacity, and make the smooth surface of overhead power transmission cable, effectively improved anti-ice-snow performance, and surface is difficult for adhering to dust, can effectively reduces noise and line loss that corona discharge produces; And, between described conductor sandwich layer and described coated skin, there is preset clearance, make composite cable there is excellent self-damping effect, reduced the vibration in composite cable running.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection range of the present utility model.
